the old testament contains parts of the old covenant, but the new testament
foretells the new covenant, and there are two covenants, one which was made at sinai - alluding to hagar and the final Prophet who would break down the idols, and would complete the new law:
I have yet many things to say unto you, but ye cannot bear them now.
Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear,
that shall he speak: and he will shew you things to come.
John 16:12-13
ask yourself - which book of law is totally memorized to the dot by it's reciters?
But this
shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
Jeremiah 31:33
This
is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them;
Hebrews 10;16
now we are aware that the Quran is a book of law which mentions the covenant at the mount and tells the children of Israel to fulfil it:
63. And remember We took your covenant and We raised above you (The towering height) of The Mount (Sinai) :
(Saying): "Hold firmly to what We have given you and bring (ever) to remembrance what is therein: Perchance ye may fear Allah."
Quran 2:63
O Children of Israel! call to mind the (special) favour which I bestowed upon you,
and fulfil your covenant with Me as I fulfil My Covenant with you, and fear none but Me.
And believe in what I reveal, confirming the revelation which is with you, and be not the first to reject Faith therein, nor sell My Signs for a small price; and fear Me, and Me alone.
And cover not Truth with falsehood, nor conceal the Truth when ye know (what it is).
And be steadfast in prayer; practise regular charity; and bow down your heads with those who bow down (in worship).
Quran 2:40-43
For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman.
23But he
who was of the bondwoman was born after the flesh; but he of the freewoman
was by promise.
24Which things are an allegory:
for these are the two covenants;
the one from the mount Sinai, which gendereth to bondage, which is Agar.
25For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children.
26But Jerusalem which is above is free, which is the mother of us all.
27For it is written, Rejoice,
thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband.
Galatians 4
it looks to me as if the part about the flesh and the spirit has been added, since the old testament clearly states that the children of Hagar would be blessed.
And God heard the voice of the lad; and the angel of God called to Hagar out of heaven, and said unto her, What aileth thee, Hagar? fear not; for God hath heard the voice of the lad where he
is.
18Arise, lift up the lad, and hold him in thine hand;
for I will make him a great nation.
Genesis 21
this happened in the desolate valley of Makkah where Abraham (pbuh) left them, and the Muslims still run between safa and marwah where hajar (pbuh) ran seeking a sighting of water.
Sing, O barren, thou
that didst not bear; break forth into singing, and cry aloud, thou
that didst not travail with child:
for more are the children of the desolate than the children of the married wife, saith the LORD.
....For the LORD hath called thee as a woman forsaken and grieved in spirit,
and a wife of youth, when thou wast refused, saith thy God.
7For a small moment have I forsaken thee; but with great mercies will I gather thee.
Isaiah 54.
and which Prophet brought a book of law after Moses? because it was foretold in Isaiah:
Hearken unto me, my people; and give ear unto me, O my nation:
for a law shall proceed from me, and I will make my judgment
to rest for a light of the people.
Isaiah 51
the REST? a new Law? do you know the Quran was revealed over 23 years in many different cities?
For precept
must be upon precept, precept upon precept; line upon line, line upon line; here a little,
and there a little:
11For with stammering lips and another tongue will he speak to this people.
12To whom he said, This is the rest wherewith ye may cause the weary to rest; and this
is the refreshing: yet they would not hear.
13But the word of the LORD was unto them precept upon precept, precept upon precept; line upon line, line upon line; here a little,
andthere a little; that they might go, and fall backward, and be broken, and snared, and taken.
14Wherefore hear the word of the LORD, ye scornful men, that rule this people which
is in Jerusalem.
Isaiah 28
it is also clear that they were awaiting a new SPECIFIC long awaited Prophet even in Jesus (pbuh)'s time - and he was different from the Christ.
And this is the record of John, when the Jews sent priests and Levites from Jerusalem to ask him,
Who art thou?
20And he confessed, and denied not; but confessed,
I am not the Christ.
21And they asked him, What then?
Art thou Elias? And he saith, I am not.
Art thou that prophet? And he answered, No.
if you go into the commentaries - you will find that "that Prophet" is the Prophet foretold in deuteronomy
